What is the name of the phenomenon where the moon appears to be larger when it is near the horizon compared to when it is high in the sky?

The phenomenon where the moon appears larger near the horizon than when it is high in the sky is known as the moon illusion. The moon illusion makes the moon look larger near the horizon compared to when it’s higher in the sky, though its actual size doesn’t change. This optical illusion is thought to be caused by factors like the way our brains perceive the moon’s size relative to objects on the horizon and the effects of atmospheric distortion.
